Be it known that l, WILLIAM I. Barnim nomi, a citizen ol. the United States, and a ,resident et lllavenporl'., in the county oi" Scott and State ol" iowa, have invented certain new and usel'ul Improvements in (lar-Trucks, of which the 'following is a full, clear, and exact description.

My invention relates to that class ot rail- \\f'ay-car trucks known as swing-motion trucks and rigid-bolsterx77 trucks and to trucks el a similar character in which the ends olE the truck-bolster do not extend into or through openings in the side frames and have their movements controlled by engagement with the vertical edges oi saidopenings.

The object ol' the invention is to dispense with the multitude et parts of which hereto- :['ore the side Vtrames and the attachments thereof were made, to make them all integral in one piece, including the means Vlor locking the ends of the transom thereto, and to otherwise cheapen, simpli'l'y, and improve the construction et the same and the cross members ol the truck. This l accomplish by the means hereinafter fully described, and as }`)articularl y pointed out in the claims.

ln the drawings, Figure l is a side view of the parts of a car-truck embodying my invention. Fig. 2 is a transverse vertical central section therethrough. Fig. il is a hori Zontal section taken on. dotted lineA 3 3, Fig. 1, looking in the direction indicated by the arrows. Fig. il is a sectional view, similar to that shown in Fig. 2, o'll a slightly-modilied construction et my invention. Fig. 5 is a side view olI the parts el" a car-truck embodying a modifiedconstruction elI my invention. Fig. is a plan view of the same with part ot the transom and also part et the upper Vllange an d weh oi.l the sid e 'tra me broken away. Fig. 7 is a transverse vertical section taken endotted line 7 7, Fig. 5.

In the drawings, A represents theupper arch oi, the side ilrame oi my improved truck; ll, the inverted arch ol" the same; (l C, parallel king-posts, and l) l) the journal-boxes. The side i'rames, including all el' these parts, are made of one piece of metal, and it 1s immaterial whether they are manufactured ol cast-steel, pressed steel, or otherwise, although east-steel is preferred.

The journal-boxes ll l) may be of any desired construction, although l prelfer to make them correspond to the requirements oi the type known as the Master lar-Builders journal-boxes, excepting that they are not ren'uivable. lhey can be provided with any suitable cover.

lnorder to reduce the weight o'l the side frames, triangular-shaped openings (t d are made therein between the upper and lower arches and the parallel columns (l, and l pre- 'ler to make an opening I) therein between said columns, although any or all oll these openings may be dispensed with.

Projecting inward l' rom the upper portion el the columns U on each side of the central opening are vertically-elongated lugs c c, the inner edges oi' which are llanged transversely toward each other. 'lhe side frames are con nected by a transom l), which is preferably channel-shaped, has the upper edges oiE its side walls flanged laterally, and has portions of its bottom and side walls cut away to reduce its weight. The edges of the ends oiE the side walls ett this transom are provided with laterallyprojecting V[langes d c', which when. the transom is lowered into its relative position during the operation of assembling the parts el the cartruck are caught and have interlockin engagement with the il'lan ged edges o'l" lugs c. lt desired, the V[langes ol" the upper edges and el? the end edges of the side walls of the transom may merge in to one another, and in this event the downward movement of the transom would be arrested when the upper end oit lugs c came in contact with the [langes elt the upper edges olf the sides oi" the transom, and thus support said transom. l prefer, however, to supply a support 'tor the ends of the transom in additionv to that given by lugs c. This l accomplish by providing the ends ell the transom withv channel-shaped extensions c, that are preferably slightly less in width and in depth than the transom ends, so as to provide an outer transverse shoulder. edges of the openings I) ol" the side trames are flanged laterally, preferably in both direel tions, and the upper portion of this opening is made wider than the lower portion. Now the length of these extensions e is slightly greater than the width of the Vflanged sill and side edges of the lower' portion of opening i), and the dimension of this lower portion of said opening is such that when said extension is inserted through the same and is seated on the sill thereof it will snugly fit in the said lower portion of said opening. The end edges of the extensions e are flanged laterally and when the parts of the truck are assembled lap against the outer edges of the Vflanges of opening l) and prevent thc withdrawal or longitudinal displacement of the transom. The height of the side walls of the extension c is preferably less than half that of the sides of the body of the transom, and when assembling the parts of the truck together the extensions are pushed through the upper portions ol,B opening of the side frame, where said opening is wide enough to permit the passage of the flanged end edges of the same, and then the said transom is lowered and the ends of the body of the transom interlock with lugs c at the same time the extensions are locked in openings of the side frame.

In Figs. 2 and S the bottom of the end portions of the transom is shown to be built with centering-bosses/ffor the support of the bolster-springs. ln Fig. 4t the corresponding portion of the bottom of the transom is dropped farther than in Fig. 2 and is suitably constructed to provide a seat E for the bearing-rollers F, which support the plate G, on which the bolster-springs are seated.

ln Figs. .5, 6, and 7 ofV the drawings l show a modified construction of my invention, in which extensions e of the transom are dispensed with and instead each side frame l is provided with an integral shelf or bracket H, which projects inward at about the center of length of the side frame, preferably below the plane of the sill of the central opening therein, (providing it has such an opening.) The vertical end edges g f/ of the side walls of the transom J are made thicker and are provided with vertical grooves 7iy 71, and the side frames are provided with lugs fr Kt, that are similar to lugs c of the preferred form of my invention, as shown in the first four Vfigures of the drawings, the flanged edges of which enter said grooves. The projection of the shelf or bracket H is such that when the lugs 7i' interlock with the end edges of the side walls of the transom J and the transom is lowered to its proper position its ends will rest on the said shelf or bracket.

l prefer to provide the transoms shown in all the forms of my invention with parallel lugs K K, that project from each side of the transom next the upper edges of its side walls and adjacent to the ends thereof. The means for suspending the brake-beams are pivotally attached to these lugs K; but the latter may be dispensed with and other constructions or means resorted to for this purpose, if desired. lf desired, as shown in Figs. 5 and 6, the journal-boxes may be provided with horizontal arms P l), that constitute alining end extensions of the side frame and are east or otherwise made in one body of metal therewith` These alining end extensions of the opposite sidc frame of the truck are used when it is intended to adapt my improvements for passenger-car trucks, and they are designed to be connected by suitable crossbars', so as to make the regulation rectangular truck-iframe for such cars when desired.
